Lease sales could produce 15 billion barrels of oil, but environmentalists say drilling would threaten already melting habitat.
A controversial proposal to extract vast supplies of oil and gas from Alaska's outer continental shelf pits America's energy needs against environmental protection. Unlike similar clashes in the past, there's a complicating factor this time: global warming.
Initial geological studies indicate that the area, roughly the size of Pennsylvania, has the potential to produce 15 billion barrels of recoverable oil and 77 trillion cubic feet of natural gas. Together with the potential energy development from lease sales offered recently in the nearby Beaufort Sea, that's enough to fuel 25 million cars and heat 46 million homes for 30 years.
"It's a significant slice of the energy we consume, based upon current rates," says Richard Ranger, an adviser with the American Petroleum Institute, an industry group. "The potential, we would argue, is of strategic significance."
The proposal comes at a time when moratoriums on new leases, as well as restrictions on exploration in the Arctic National Wildlife Refuge and two areas of the outer continental shelf in the Atlantic and Pacific, "have had the effect of really limiting where we can look for energy Americans need," says Mr. Ranger.
At the same time, with new exploration and drilling technologies, the odds of success are becoming more favorable.
